Webinar: Converting to Wet Stack. Design, Economics, Operation, and Issues

Date: September 20, 2017
Time: 7:00 am EDT (4.30 pm IST)
Duration: 60 minutes

It is more and more important for coal fired power stations to maximize their operational efficiency and minimize their emissions. Changing over to wet stack operation can bring economic and environmental advantages, but requires proper design to avoid major operational issues. The webcast discussed operating issues of wet stacks, detailed what is provided from a wet stack model study, provided tips on maintenance of the wet stack liquid collection system, reviewed the economic and environmental impacts of liner material and stack options available today, discussed the process of having a glass borosilicate block liner system installed, and presented a case study of converting an existing stack to wet operation.
